Lewis Hamilton has issued a message of support to the Queen following news of her health status on Thursday.
Buckingham Palace issued a statement on Her Majesty's health and said doctors were "concerned", with members of the Royal Family travelling to Balmoral to be by her side.
An outpouring of support has come from across the globe, with world leaders and political figures among those to comment on the matter, and seven-time Formula One world champion Hamilton also spoke on the matter.
"It's definitely concerning. I think she's been such a strong leader for a such a long time, so resilient," he said in a press conference ahead of Sunday's race at Monza.
"I know she's always been a real fighter, so my thoughts are with her. I don't have any more information, I don't know any more about the situation.
"My thoughts are with the family, my thoughts are with her, my prayers are with them and I'm hoping for better news soon."
Hamilton was knighted by the Queen last year, days after he narrowly missed out on what would have been a record-breaking world title.
